<div dir="ltr">Dear Prof. Blaha, dear All,<br><div><br></div><div>Thank you for the rapid response. I tested lapw7 and it works nicely, I can plot the phase.</div><div><br></div><div>I was wondering about the meaning of the phase for the periodic system. Correct me if I'm wrong, but the total phase would include the Bloch envelope exp(i.k.r) and the intra-unit-cell phase differences. lapw7 allows plotting more than a single unit cell (in case of the slab, it is naturally the "parallel" direction). Would the phase then include the Bloch envelope or not? I have a feeling it does include the Bloch envelope, is that correct?</div><div><br></div><div>Best,</div><div>Lukasz</div><div><br></div><div><pre class="gmail-moz-signature" cols="72">--

This means of k-point k and band n, which must be specified as input.<br>

Check the UG, it is quite similar to lapw5 and the plots can be <br>
visualized in xcrysden.<br>
